Fig 13. Comparison of the CI widths of three estimators $\{{\widehat{p}}_s,{\widehat{GR}}_s,{\widehat{GR}}_r\}$ using the three different estimation methods, when the observation noise parameter is set to c = 500.

Results are presented as in Fig 12. This figure demonstrates that the advantages of the live cell image method in estimation precision become less significant as the standard deviation of observation noise increases to 50% of the initial cell count.
